IMPROVEMENT IN' MODE 0F LUBRIGATING JOURNALS.

To ALL wHoM IT MAY` ooNoERN:

Be it known that I, ISAAC P. WENDELL, of thev city and county of Philadelphia, and State of Pennsylvania, l

have` invented a new and useful Improvement in Lubricating the Journals of Gar and other Shafts; and I do panying drawings, and to the letters of reference marked thereon.

The nature of my invention and improvement consists ina novel mode ofsupplying oil to the journals of car and other shafts, by creating avacuum in a supply-box, substantiallyas follows. In the accompanying drawingsl i V Figure 1 is a plan or top view of the supply-box A, and parts attached to the same.

Figure 2 is a vertical cross-section of same, in combination with the journal E.

Like letters in both the gures indicatethe same parts.

A is a box for containing the lubricating material; B is a cap plate of the box, that has'a curved longitudinal groove, a, to which lthe oil is supplied to lubricate the journal, by means of spiral or twisted wires, C, arranged in the vertical tubes D, which project from the under side of said cap plate to within a short distance ofthe bottom of the box, so that the ends of the tubes shall always be inthe oil. The lower ends ofthe wires C rest upon the bottom of the box, and the upper ends extend to the upper curved surface of the plate B, so as to keep said surface supplied with oil to lubricate the journal. The surface is kept up so as to have agentle pressure against the journal, by means of springs under the supply-bc'x,vsaid springs resting upon the upper surface of the bottomof the journal-box. As said arrangement of the springs with the boxes is fully shown in an application for a patent already granted to me, I deem a further description thereof unnecessary. There are small holes, b, in the cap plate B, to admit air in the box A, for the purpose I will presently describe.

The operation is as follows: As the journalErevolves, a vacuum is created in the tubes D, which causes the oil to ascend up the wires C to supply the journal, the oil spreading on the curved surface of the Aplate B, which gently touches the journal. The atmospheric air presses from without through the small-openings, b, of the cap piece B, into the supplyfbox A, which gives an increased tendency of the oil to ascend the wires C, as it presses upon the upper surface of the oil within the box. This mode of lubricating journals may be frequently applied to the journals of mills and other shafts. It may,`however, sometimes be found expedient to modify the arrangement. Instead of the'spiral wires and tubes I), there may be a longitudinal slotl in the cap piece B, which shall extend low enough into the box A to be always in communication with the oil, so that the latter may ow up the sides ofthe slot as a vacuum is created in the same. The wires C may be dispensed with by making the tubes small to 4easily'form vacuums.

Having thus fully described my improvement in lubricating the journals of car and other shafts, what I claim therein as new, and desire to secure by' Letters Patent, is-

An oil-box, A, havinga tube D, in combination with plate B, (having orifices 6,) and journal E, substantially as described. v.

In testimonythat the above is my invention, I have hereunto set `Amy hand and affixed my seal this seven' teenth day of July, 1866.
